After complaining to the US-owned restaurant chain in East Ham, London, he was offered an apology and told it was no "normal fly."

Horrified Hardip, who vowed never to return, said: "I'd just finished a gym session and went into KFC for something to eat.

"I then bit into a chicken wing and saw something black there. It was a fly and it was a big one."

He added: "I stopped eating straight away - it was horrible."

Mr Singh took the wing and dead insect to the counter and was offered another snack by an assistant.

Vile: Staff offered Hardip a refund and a replacement meal

"I told them I didn't want to eat the chicken. I just wanted my money back.

"This has put me off KFC for ever," said the regular customer.

"It's totally disgusting, you don't know where that fly's been.

"If I ate it I could have suffered food poisoning or even worse. The whole chicken could have been contaminated."

Fahad Masood, manager of East Ham KFC, said they had "apologised" to Mr Singh.

Mr Masood said: "This has never happened here before. It's not a normal fly - it's a seasonal fly. I think it was on the bread somewhere.

"It might have even landed as he was walking from the counter. We contact the pest control every week to avoid such incidents."

A spokesperson for KFC said: "We are very sorry to hear about Mr Singh's experience and would like to reassure customers that our East Ham restaurant has a food hygiene rating of five out of five stars, meaning that the business was found to have very good hygiene standards.

"As soon we were made aware of the situation we apologised on the spot and offered a refund and a replacement meal.

"Mr Singh accepted an additional side in store and no complaint was made to our care line."
